What is a chip resistor? What are the basic structure and performance parameters of a chip resistor

Chip resistor is a common electronic component, XC95288XL-10PQG208C, used for limiting current, adjusting the resistance value of circuits, etc. It features miniaturization, high reliability, and low cost, and is widely used in electronic devices. The following will introduce the basic structure, performance parameters, working principle, installation method, classification, identification method, purchase and selection, as well as the development history of chip resistors.diode

1. Basic structure:

The basic structure of a chip resistor consists of a resistive material, electrodes, an insulating layer, and a packaging material. The resistive material is typically composed of metal alloys or carbon films. The electrodes are used to receive and conduct current, the insulating layer serves to isolate the electrodes from the circuit board, and the packaging material protects the resistive material and electrodes.

II. Performance parameters:

1. Rated Power: It indicates the maximum power at which a chip resistor can operate stably. Common rated powers include 1/8W, 1/4W, 1/2W, etc.

2. Rated Resistance: It indicates the nominal resistance value of the chip resistor. Common rated resistance values include 10Ω, 100Ω, 1kΩ, etc.diode

3. Rated Voltage: It indicates the maximum voltage that a chip resistor can withstand. Common rated voltages include 50V, 100V, etc.

4. Tolerance: It represents the error between the actual resistance value and the nominal resistance value of a chip resistor. Common tolerances include ±1%, ±5%, etc.diode

5. Temperature Coefficient: It indicates the degree to which the resistance value of a chip resistor changes with temperature. Common temperature coefficients include ±100ppm/℃, ±200ppm/℃, etc.
